Account Limits in the BitBox: Insights and Improvements

The BitBox is one of the most renowned hardware wallets on the market, offering users a secure way to manage their cryptocurrencies. A recent update to the BitBox software has introduced several notable improvements, including the removal of the previous limit of five accounts per wallet. In this article, we will take a detailed look at the background and benefits of this new feature.

Background: The Structure of a Wallet

A wallet, as used in the BitBox, is defined by a seed phrase. This seed phrase, consisting of 12, 18, or 24 recovery words, can be supplemented with an optional passphrase. This combination allows the creation and use of multiple accounts within a single wallet, eliminating the need to manage multiple separate wallets.

The Original Limitation

Previously, the number of accounts within a wallet was limited to five. This restriction was primarily due to performance considerations. Each account within a wallet has numerous addresses that the wallet must search through to identify existing Bitcoins and transactions. This search is based on derivation paths that extend from the wallet through various script types down to individual addresses.

The wallet must consider so-called “gap limits”—a threshold after which the wallet stops searching for addresses if a certain number of consecutive addresses are unused. By default, this limit is 20 addresses. With each additional account, the effort required for this search multiplies, leading to an exponential increase in search time and impacting the wallet’s performance.

Removal of Account Limits

The new BitBox update has removed this limit. This was made possible by implementing an improved caching mechanism that automatically discovers and manages accounts. As a result, the wallet’s efficiency has significantly increased, allowing the BitBox to support an unlimited number of accounts without noticeable performance degradation.

Benefits of the New Structure

The ability to manage multiple accounts within a single wallet offers numerous advantages:

1. Organization: Users can organize their Bitcoins into different accounts, such as for daily expenses, long-term savings, or separate accounts for family members.
2. Privacy: Dividing Bitcoins across multiple accounts helps maintain privacy.
3. Flexibility: Users can set up accounts for specific purposes like regular purchases or salary deposits without having to manage multiple seed phrases.

Self-Generated Seed Phrases

Another interesting feature of the BitBox is the ability to generate seed phrases by rolling dice. This can be particularly appealing to users who want maximum control over their wallets. The provided instructions, which can be used offline, ensure that the process is safe and reliable. It is important to use high-quality dice to ensure true randomness.

Using Self-Generated Seed Phrases with the BitBox

Users can use their rolled seed phrases with the BitBox by resetting the wallet and selecting the restore option. The BitBox supports this process and will display the valid words for the checksum of the seed phrase, allowing a valid wallet to be created.

Conclusion

The latest updates to the BitBox bring significant improvements in terms of user-friendliness and performance. The removal of account limits and the ability to generate seed phrases by rolling dice provide users with greater flexibility and control. The BitBox remains one of the most secure and user-friendly hardware wallets on the market.
